## How to use the Rule of 72 & its Formula?

It is possible to calculate how long it will require for an investment to grow to double in value using the Rule of 72, but it's crucial to remember that this is merely a calculation. Several variables, such as the rate of interest, the frequency of compounding, and the length of time the investment is held, will affect how long it actually takes for an ownership stake to double in value.

You must be aware of your investment's annual interest rate in order to apply the Rule of 72. This can be a return on a mutual fund's investments, the rate of interest on a savings account, or any other investment that generates income.

To find the total amount of years it needs for the investment to grow by twofold in value, divide 72 by the yearly interest rate after you have it. For instance, it will take roughly 9 years (72 x 8 = 9) for your investment to grow by twofold in value if the annual interest rate is 8%.

## Limitations of the Rule of 72

The Rule of 72 is a valuable tool for determining when an investment will double in value, but it is crucial to be aware of its limits. The fact that it presumes a constant rate of return is one of its main drawbacks. It is actually challenging to anticipate how long it will take for a stock to double in value because the rate for return on a given investment might vary over time.

The Rule of 72 also counts on annual compounding of interest. The actual time it takes for a stock to double in value will be less than the estimate provided by the Rule of 72 if interest is added up more regularly, such as monthly or daily.

## Conclusion on Rule of 72

A straightforward and practical method for determining how long it takes for a stake to double in value is the Rule of 72. You may quickly determine how long it will take your money to double by dividing 72 by the yearly interest rate.

The Rule of 72 is merely a guide, so it's crucial to keep in mind that there are a number of variables that might determine how long it actually requires for an investment to grow to double in value. Learn about the rule of 72 in stock market and how to utlise in the above article.
